Switch Port Attribute Default Values

You can configure attribute default values for various switch port attributes. These attributes will be
applied globally to all future switch port configurations, even if you do not individually specify them at
that time.
To configure switch port attributes, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# no system default
switchport shutdown
switch(config)#
switch(config)# system default
switchport shutdown
switch(config)#
switch(config)# system default
switchport trunk mode auto
switch(config)#

About SFP Transmitter Types

The small form-factor pluggable (SFP) hardware transmitters are identified by their acronyms when
displayed in the show interface brief command. If the related SFP has a Cisco-assigned extended ID,
then the show interface and show interface brief commands display the ID instead of the transmitter
type. The show interface transceiver command and the show interface fcslot/port transceiver
command display both values for Cisco supported SFPs.
